Evaluation of the Suitability of a Single-Cylinder Engine for Use in FSAE 2006-32-0053

This paper discusses the suitability of a 450 cm³, single-cylinder engine for use in the FSAE competition. The rules of the FSAE and Formula Student competitions permit the use of four-stroke engines of up to 610 cm³ capacity and with forced induction [1]. Most teams design cars around normally aspirated four-cylinder 600 cm³ engines. The suitability of an alternative single-cylinder engine is examined here through engine simulation. The simulation model of the single-cylinder engine is described and has been verified using published data on the engine's predecessor. This model is then used to find the most suitable configuration for use in the FSAE competition. It is shown that in a normally aspirated format, the single-cylinder engine is unlikely to be competitive. If supercharging is applied however, a very attractive overall vehicle package is found to result.
